Energy and Energy Transformations

law of conservation of energy -energy can be transformed from one form into another or transferred from one region to another, but energy cannot be created or destroyed
friction a force that resists the sliding of two surfaces that are touching
temperature the measure of the average kinetic energy of the particles in a material
heat the movement of thermal energy from a region of higher temperature to a region of lower temperature
conduction the transfer of thermal energy by collisions between particles in matter
radiation the transfer of thermal energy by electromagnetic waves
convection the transfer of thermal energy by the movement of the particles from one part of a material to another
vaporization the change of state from a liquid to a gas
thermal conductor a material in which thermal energy moves quickly
thermal insulator a material in which thermal energy moves slowly
